From Anchor to Riverside

 Anchor, an audio recording app, used to be coupled with Wordpress. Audio recordings made with Anchor could be automatically uploaded to the app called Podcasters for Spotify. The podcast one creates would be automatically featured in the Spotify directory. 

But a few years ago, the two were decoupled. Podcasters for Spotify coupled with Riverside, an audio recording app somewhat like Anchor. 

Then a few months ago, Podcasters for Spotify was renamed Spotify for Creators. It has continued to use Riverside as the built-in recording app. An audio made with Riverside is automatically added to one's podcast.
